Someone please help me with this!! <3

Answer 1

Answer: Um, your sum should be 4.

Step-by-step explanation: The sum of an infinite geometric series can be found using the formula
`(a)/(1-r)` where a is the first term and r is the ratio between the successive terms.

For
`a_(1)`, find the first term in the series by substituting in the lower bound and simplifying: a=1.

For r, find the ratio of successive terms by plugging into the formula
`r=(a_(n+1))/(a_(n))` and simplifying:
`r=(3)/(4)`.

For 1–r, substitute the values of the ratio and first term into the sum formula:
`(1)/(1-(3)/(4))`; ∴, your sum should be 4.
